ADJUSTABLE BRUSH HANDLE.

Application led June 12, 1923.

To all fro/0m 'it may concern.'

Be it known that GEORGE NiTz, citizen ot' the United State-s, residing at Omaha, in

the county of Douglas and State of Nebraska, has invented certain new and useful Improvements in Adjustable Brush Handles, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to adjustable brush handles, `and has for its object to provide Va device of this character particularly adapted for use in connection with relatively long sweeping or dusting brushes, and has for its object to provide an adjustable handle which may be adjusted at various angles in relation to the brush head according to the nature of the work being done, such for instance as brushing'walls, floors or ceilings. Also to support the brush handle from spaced brackets spaced a substantial dist-ance from the center of the brush head, thereby allowing proper leverage in especially long brushes, and atthe same time obviating the present use of a brush handle which is threaded into the brush head, which easily becomes worn and unscrewed when used in connection with relatively long brush heads where the leverage is great during the brushing o eration.

A urther object is to provide the brush handle with a right angularly disposed member, the ends of which are provided with toothed discs which cooperate with toothed discs carried by the brush head. The toothed discs when interengaged form means for holding the brush handle at various angles to the brush head.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a view in elevation of the brush.

Figure 2 is a side elevation of the brush showing a handle adjusted to the position in the same plane as the brush.

Figure 3` is an enlarged Sectional view Serial No. 644,893.

through a portion of the brush head and a pair of interengaged toothed discs.

Figure 1l is a view showing one of the lootied discs which is carried by the brush Figure 5 is an end .view of the brush handle shaft showing the toothed disc carried thereby,

Referring to ,the drawing, the numeral l designates a. brush head of the dust brush type, which isrelatively long, and is generally 18 inches in length or longer. In brushes of this character, at the present time, handles are threaded or screwed into a threaded aperture of the brush head centrally thereof. It has been found that where conventional forms of handles are used, on account of the great length of the brush, the brush easily becomes loose or unscrewed or the threads become stripped during use. It has also been found that brushes of this character are used for sweeping floors, walls and ceilings and a handle secured to the brush at a xed angle renders some of its operations, especially the overhead ones, dificult. To obviate thel above difficulties Vthe handle member 2 is adjustably connected to the brush head 1 in a manner whereby it may be adjusted to various angles in relation to the brush head as shown in dotted lines in Figure 2. It will be seen that by adjusting the handle 2 to various angles, the handle may be adjusted according to the nature of the sweeping or brushing operation.

The lower end 3 of the handle 2 is provided with a rightangularly disposed shaft 4, to which the handle 2 is secured substantially centrally of the shaft 4. The shaft 4 is relatively long and adjacent its outer ends is provided with discs 5, the outer faces of which are provided with radially disposed teeth 6, which teeth engage radially disposed teeth 7 carried by discs 8, and through a rtures 9 of which discs 8, the ends of the s aft 4 extend. Threaded on the outer ends of the shaft 4 are nuts 10, which nuts, when tightened securely lock the interengaged discs 5 and 8 together, thereb lookin the handle 2 positively at any ang e to which it may have been adjusted. When the nuts 10 are loosened, the handle 2 may be adjusted to various angles in relation to the brush head 1 by grasping the brush head 1 and handle 2 and moving the same to the proper position in relation to each other. The teeth t and 6 are relatively small and the Shanks l1 of the discs 8 have suflicent spring action to allow the teeth to cam past each other. The Shanks 11 of the discs 8- are provided with flanges l2 which engage the upper-side of the brush head l and extend through the brush head l and are provided with nuts 13 whereby the discs 8 may be securely attached to the brush head. It will be seen that the discs Se. and 5 are locatedv substantial distances from the `center of the brushhead and consequentlyf'` the leverage during a sweeping operation is reduced to a minimum, thereby facilitating. the sweeping operation.

From the above it will be seenY that an adjustable brushrhandlle is provided. for use in connection with relatively long brushes, which may be easily and quickly adjusted to variousanglesdn relation to the brush head,and the handle is positively attached to the brush head thereby obviating the present difficulty experienced where brush handles are threaded into the brush head. The invention having been set forth what is claimed as new and useful is The combination with a relatively long brush head, of an adjustable handle carried thereby, said handle being secured centrally to a transversely disposed shaft, integral toothed dises carried by said shaft, toothed discs carried by the brush head at points spaced from its center, and through which discs the ends of the shaft extend, Said toothed discs cooperating to hold the handle at-various angles in relation to the brush head and nuts threaded ou the outer ends of the shaft and flexible shafts connecting the brush carried discs to the brush, whereby duringa handle adjusting operation the lbrush carried discs will spring outwardly in opposite directions.

In testimony whereof I hereunto affix my signature.

GEORGE NITZ.
